The JAM 150 Extension has been designed for combination with the JAM 150 compact amplifier, providing a 300W system that plays a similar role to the SIDE/UNICO combination in providing more output and better sound dispersion.

Perfect as a second stage monitor for duo performances, the JAM 150/Extension combination can also be used as a compact active PA system that suits a range of activities including some small-scale DJ applications.

As a single, stand-alone loudspeaker system, the JAM 150 Extension can be teamed with a preamp such as Yellow Blender or Yellow Single for small-scale solo performances.
